摘要： A buffer management mechanism in a multi-core processor for use on a modem in a telecommunications network is described herein. The buffer management mechanism includes a buffer module that provides buffer management services for one or more Layer 2 applications, wherein the buffer module at least provides a user space application interface to application software running in user space. The buffer management mechanism also includes a buffer manager that manages a plurality of separate pools of tokens, wherein the tokens comprise pointers to memory areas in external memory. In addition, the buffer management mechanism includes a custom driver that manages Data Path Acceleration Architecture (DPAA) resources including buffer pools and frame queues to be used for user plane data distributing.

摘要： A computer-implemented system and method for a lock-less, zero data copy messaging mechanism in a multi-core processor for use on a modem in a telecommunications network are described herein. The method includes, for each of a plurality of processing cores, acquiring a kernel to user-space (K-U) mapped buffer and corresponding buffer descriptor, inserting a data packet into the buffer; and inserting the buffer descriptor into a circular buffer. The method further includes creating a frame descriptor containing the K-U mapped buffer pointer, inserting the frame descriptor onto a frame queue specified by a dynamic PCD rule mapping IP addresses to frame queues, and creating a buffer descriptor from the frame descriptor.

摘要： A new sub-system, the core abstraction layer (CAL), is introduced to the middleware layer of the multi-core processor based modem board. This new module provides an abstraction for the multi-core FSL P4080 processor and its DPAA. For the deployment of this modem board, the CAL will provide various services such as zero copy lock free buffer management scheme to LTE L2 application, and the support for the new backplane Ethernet driver (BED) interface for the RLC SDU transmission and reception to and from the controller board for multi-cell configuration.

摘要： A method and system that helps to ensure that any cell crash (i.e., an involuntarily action occurring as a result of a software bug or malfunction) is localized to a single cell on a single modem board that supports multi-cell configuration. In this regard, the control plane and the remaining cells that are configured on the modem board should remain operational. Further the operator should be able to choose to take corrective action (i.e., reboot, reconfigure, delete, or create) with regard to a cell on the modem board without impacting the operations of the other configured cells.

摘要： A user equipment determines a set of licensed and unlicensed frequency bands that are available for wireless communication. The user equipment selects a first subset of the set as targets for a handover involving at least one unlicensed frequency band and transmits information indicating the first subset. A base station receives information indicating a first subset of a set of licensed and unlicensed frequency bands. The first subset are targets for a handover of user equipment involving at least one unlicensed frequency band. The base station selects a second subset based on the first subset and transmits information indicating the second subset.

摘要： Nodes in a wireless communication system can mitigate interference in unlicensed frequency bands by coordinating downlink transmissions. The nodes may negotiate, based on messages exchanged over an interface between a first node and at least one second node, time intervals for downlink transmissions by the first node and the at least one second node over a channel of an unlicensed frequency band in response to the at least one second node transmitting over the channel of the unlicensed frequency band.
